1. CONTEXT Solving these problems requires new solutions on the intersection
Recent years witnessed an exponential growth of data providers of data integration, multi-domain search, deep web extraction, and
available on the Web. These providers offer a plethora of differ- information extraction. In this edition, a particular focus is the con-
ent ways of accessing their data sources, spanning from APIs over struction of search services and knowledge bases from unstructured
proprietary query languages (such as Yahoo! Query Language, web data and the deep web.
YQL) to endpoints accessible through standard query languages
(e.g., SPARQL). At the same time, data is increasingly being la-
beled, tagged, and linked with existing data, partially due to social
